ToneBird

ToneBird is an AI reply assistant for Mac and Windows that drafts the next message in a conversation in your own voice, right inside the apps you already use: Gmail, Slack, WhatsApp, iMessage, Google Chat, LinkedIn, Reddit, Instagram, Discord, WeChat and Lark. Its core idea is that a good reply depends on who you're talking to and what you've already said.

What is ToneBird used for?

It helps when a message is hard to answer: a client chasing a date for the second time, a manager in a hurry or a tricky renewal. ToneBird keeps relationship memory with a card for each person, recalls what you promised in earlier threads and checks connected documents, like a proposal PDF, to pull in the exact figure. It adjusts the wording to each person, so a client waiting on a deadline gets a different reply from a teammate checking in.

How does ToneBird work?

You open it by clicking the orb or tapping Option twice on Mac (Ctrl on Windows). It offers three reply options you can flip through with the arrow keys, tweak with buttons like "more precise", "warmer" or "add humor", and insert into the reply box; it never sends anything for you. It also spots agreed meeting times and prepares the event in Google Calendar or Apple Calendar, and gathers promised quotes, unanswered questions and dates to confirm into a follow-up list. It works across languages and can show a translation of the draft.

Who is ToneBird for?

• Freelancers and consultants juggling many clients at once.
• Salespeople who need to remember deals and nuances for each account.
• Professionals replying all day in Slack, email and social apps.

ToneBird pros and cons

Privacy is the standout: your tone profile, contact cards and learned corrections stay on your device, and you approve each learned adjustment before it changes how ToneBird writes. On the downside, it's a desktop app only, daily drafts and remembered contacts are capped by tier, and the site says paid tiers can't be purchased there yet.
